Abstract: A mouse includes a main body and a control circuit. A left button, a number of pressure sensors, a right button, and a control button are positioned on the main body. The control circuit includes a control unit, an acceleration sensor, and a wireless transmitter. The left button, the pressure sensors, the right button, the control button, the acceleration sensor, and the wireless transmitter are connected to the control unit. When the mouse is placed in the mouth of a user, the left button, the pressure sensors, and the right button are operated by the tongue of the user. The control button is bitten by the teeth of the user, to turn on the acceleration sensor. The acceleration sensor senses movement of the head of the user, and cooperates with the control unit and the wireless transmitter to control a cursor of a computer to move.

Abstract: A foldable keyboard includes a first keyboard portion, a second keyboard portion, a third keyboard portion rotatably connected to each other; and a control unit. The control unit includes a detecting module and a processing module. The detecting module detects relative distance between the first keyboard portion, the second keyboard portion and the third keyboard portion, and outputting an electronic signal to the processing module. The processing module receives the electronic signal and computes a distance value. The processing module compares the distance vale with a predetermined standard range value for determining different work modes of the keyboard.

Abstract: An exemplary hardware component protecting method obtains an identifier inputted by a user. The method outputs an unlocking signal to trigger an electric lock corresponding to one locked hardware component to unlock a case corresponding to the one locked hardware component from the housing when the inputted identifier matches an identifier stored in the locked hardware component. The method also outputs a locking signal to trigger the electric lock corresponding to one newly installed hardware component to lock the case corresponding to the newly installed hardware component to the housing when the identifier stored in the hardware component matches an authorized identifier from a manufacturer's hardware support website.

Abstract: A display device includes a display screen, a distance sensing unit, set on an appropriate position of the display screen to sense a relative distance from a user to the display device; a processing unit comprising a projection position determining module, a stretching area determining module, and a display control module. The projection position determining module calculates a projected position of the user on the display screen according to a position of the distance sensing unit on the display screen, the projected position is the position on the display screen where the user is projected on. The stretching area determining module determines an area needed to be stretched on the display screen according to the projected position on the display screen and a predetermined distance. The display control module stretches content displayed on the area needed to be stretched according to a predetermined percentage. The display method is also provided.

Abstract: A mobile computer includes a housing, an electrical connector located on the housing and a game controller. The game controller is detachably connected to housing and includes a main body, a connection assembly and a connector. The connection assembly is rotatably connected to the main body. The connector is located within the connection assembly, and is electrically connected to the electrical connector of the mobile computer, the game controller is rotatably connected to the mobile computer through the connection assembly, and the game controller communicates with the mobile computer through the connector and the electrical connector.

Abstract: A touch input device includes a first storage module, a second storage module, a touch input unit, a first detecting unit, a second detecting unit, a processing module and a housing. When one or both of the first and the second detecting units detect a touch of a user on one or two corners of the housing, the processing module will make one or two soft keyboards be shown on the touch input unit according to position information stored in the first and the second storage modules. The user can use single hand or both hands to input a command. The disclosure further provides a touch input method.

Abstract: A mouse assembly used for a computer includes a first mouse module and a second mouse module. The first mouse module includes a first connector, and the second mouse module includes a second connector. The second mouse module is detachably and electrically connected to the first mouse module through the first connector and the second connector. When the first connector is mechanically and electrically connected to the second connector, the first mouse module and the second mouse module are assembled together, and the mouse assembly is used as a wireless mouse. When the first connector is mechanically disconnected from the second connector, the first mouse module intercommunicates with the second mouse module, and the mouse assembly is used as touch input device.
